IMPROVEMENT IN HANDLES FOR KNIVES.

Specification forming part of Letters Patent No. 103375, dated May 24,1870.

To `all whom it may concern:

Be it known that I, JACOB B. BAILEY, of the city and State of New York,have invented an Improvement in Handles for Knives; and the following isdeclared to be a correct description thereof.

Handles for tableknives have been made hollow, and either the halvessoldered together or the entire handle cast upona core. In both cases itis difficult to obtain a perfect handle, free from perforations orflaws. VMetal bolsters have also been' cast upon the knife, and usedwith wooden and other handles.

In knives where the bolster is cast upon the blade the shrinkage of themetal as it cools frequently causes a very narrow opening between thebolster and the blade, and into this the materials employed insilver-plating are sure to pass, and these afterward injure the finishedblade when exposed to vmoisture or atmospheric influences. This openingis further increased by bending up and breaking or cutting off thefeather or spur of metal that frequently passes out between the mold andthe blade in casting, especially as the bolster at the point of union isusually very thinand easily bent. l

Bolsters have been made upon the ends and shanks of knife-blades, andthe blade has been perforated at this point for the cast metal or thebolster to run through 5 but knives made with these bolsters were notadapted to being plated because the handlewas made in askeleton form orhollow, to receive pieces of wood or bone, and it is found in practicethat handles of this description cannot be plated reliably, because thesolution employed penetrates the joints, crevices, or openings.

handles; and it consists in a solid metal handle l cast upon the tang ofthe blade, with the cast metal extended up around the base of the bladeto form the bolster, with a square shoulder at its union withthe blade,so that said bolster will not be bent up by the breaking off of any linor spur-of metal that may pass out between the blade and the mold.

In the drawings, Figure l is a side view, with part of the handle insection; and Fig. 2 is a section at the line .r x.

The blade a is made with a shank or tang, b, passing into the handle c,which handle and the bolster e are of metal east around the tang b andbase of the blade a. The holes through the blade at i i allow the eastmetal to tie the around the base. of the blade, to form the boll sterwith the square shoulder, as and for the purposes set forth.
